When embedding WebView
in an application and loading html-pages in it, JavaScripts alert()
/confirm()
/etc. do not work.
Looking around in the documentation, there are no related settings in WebPreferences
- the only thing that looks related are WebUIDelegate
s -(void)webView:runJavaScriptAlertPanelWithMessage:initiatedByFrame:
etc ... but implementing these would mean writing custom dialogs for these which seems pretty redundant...
I don't need a custom WebUIDelegate
and would like to continue just using the default one.
Surely there has to be some way to simply enable alert()
et al, but how?
Here is a sample code that will do the basic job. You need however to make sure that this object is registered as a UIDelegate for the WebView.
- (void)webView:(WebView *)sender runJavaScriptAlertPanelWithMessage:(NSString *)message initiatedByFrame:(WebFrame *)frame {
NSAlert *alert = [[NSAlert alloc] init];
[alert addButtonWithTitle:@"OK"];
[alert setMessageText:message];
[alert runModal];
[alert release];
}
It turns out there is simply no default WebUIDelegate
set - Apple seems to expect everyone to implement the same basic features for themselves.
